lvy invention is designed to provide means for relieving the load'ot' fa journal box von a wheel axle and transmitting such load to the wheel adjacent the rimthereof through a jack having means for ldeveloping the powertul vtorce necessary for lifting the load within-the narrowA space available between the journal bon and the wheelflange. My

mechanism .for accomplishing this' object is,

1G however, adapted for other uses where powA- erful pressure must be developed'within a narrow space and particularly where the rest for the jack is oset from the centerof gravity O the load. Y, i

In the preferred embodiment of my improvements, I provide a supporting foot or stanchion having scalpriform edges adapted' to rest upon the iange of a wheel adjacent its web and to support wedge mechanism for being operable by revoluble means located at a distance from the ram. and'where its operation will notjbe interferedV with` by overhang ofthe journal box. By utilizing the wheel iiange as a footing for the jack, I obviate any tendencyof the wheel to rise with the journal box or any necessity for providing any additional or foundation for the jack capable of supporting the load.

The characteristic features and advantages tot my improvements will more fully appear from the following description of a preferred embodiment'and application of my invention, and the accompanying dravving's' in illustration thereof.'V i i' l ln 'the drawings, Fig. V1 is a perspective view= ofv av prei-'erred embodiment of my invention in position for lifting a journal box, parts being` broken away; Fig. 2 is a longitudinal .vertical sectional viewV ot the jack shown in Fig. 1; Fig. 3 isa horizontal sectional view on the line 3-3 of Fig. 2; Fig. 4 is atransverse sectional ,view on the line T45 oiFig.. v2; Fig. 5 is a transverse sectional view on theline .5f-5,. oit'yFig. 2; Fig. 6 is a transverse sectional view on the line 6 6 of Fig.' 2; Fig. 7 Vis a side elevationof a stepped A. filler 'barbier insertiony between the ram or a5 moving a ram into engagement with and lifting arjournal box, therwedge meehanism' plunger and the, load; Fig. 8 is an elevationy ofia handle by which the jack may be oper# V ated; and'Fig. Snisan elevation of a which the jackL may be operated.
